So I am hearing now from a few reputable engine builders that Penn Grade semi synthetic oil is not the go to oil these days and they are having problems with it. They said on some of their high end builds, the oil is not working out and they are burning up parts. I need to buy oil and now not sure if the non synthetic dino oil is the way to go. Any thoughts?

We stopped using BP years ago. A lot of the Engines that come in for freshen ups that run BP have worn rocker shafts and Piston Pins. We only use Driven Brand Oil, every Big Block we Dyno has BR50 in it. In a lot of our high HP Drag engine we use XP3 after dyno but in most cases the HR series oil is a good choice. We use the 15/50 in our bracket style engines.

Many of my buddies run Brad Penn. The stuff feels slippery & doesn't like to come off of your skin but I have never been a fan either for the money. I just run whatever brand oil 10W30 is on sale at that moment when I am in the parts store. Never had an issue with any of them.

At work we just run 10W30 conventional in all of our crate engines & for the race engines we use the Rotella 15W40 Diesel oil.

Agree with all of the above!!

I run the same but also put some Lucas break in additive with it at each oil change.

My issue w/ Lucas, and it could be completely irrational, is that I suspect their Marketing Dept has as much influence on what goes into their oils as their Engineering Dept. Have you seen some of the ZDDP #s they put in some of their oils? They are waaaaay off the "reasonable amount" scale and jumping right into the "too much of anything is NOT a good thing" range.

It also appeared for quite a while that Lucas must have been giving sh!tloads of free product (or buying sh!tloads of advertising) to all the major magazines -- at least the ones that are left -- since virtually every dyno test article they ran used Lucas oil.

I'll pass, thanks.
